摘　　要：以JTB-0.8×0.6A型提升绞车滚筒结构为研究对象,对提升绞车以及滚筒结构进行简要概述,利用SolidWorks和ANSYS软件建立了滚筒结构的数值模型。分析发现滚筒最大应力为231.45 MPa,最大变形为1.302 9 mm,最大应力几乎接近45号钢的许用应力237 MPa,所以滚筒容易出现故障问题。根据最新规范标准要求和经验公式,对滚筒直径和宽度进行优化设计计算,所得结果分别为3 000 mm和3 752 mm。将优化后的滚筒结构进行数值分析,最大应力和变形分别降低了20.65%、19.77%。将优化后的滚筒结构应用到提升绞车工程实践中,发现达到了预期效果。Taking the drum structure of JTB-0.8×0.6A hoisting winch as the research object,a brief overview of the hoisting winch and the drum structure was conducted,and the numerical model of the drum structure was established by using SolidWorks and ANSYS software.It is found that the maximum stress of the drum is 231.45 MPa and the maximum deformation is 1.3029 mm,and the maximum stress is almost close to the permissible stress of No.45 steel 237 MPa,so the drum is prone to failure problems.According to the latest specification and empirical formula,the optimised design of the drum diameter and width were calculated to be 3,000 mm and 3,752 mm respectively,and the numerical analysis of the optimised drum structure showed that the maximum stress and deformation were reduced by 20.65%and 19.77%respectively.The optimised drum structure was applied to the hoisting winch engineering practice and found to achieve the expected results.
